How sound are our ultra-light axion approximations?

Tessa Cookmeyer, Daniel Grin, Tristan L. Smith

Ultra-light axions (ULAs) are a promising dark-matter candidate. ULAs may have implications for small-scale challenges to the CDM model, and arise in string scenarios. ULAs are…

Spin Wave Analysis of Low-Temperature Thermal Hall Effect in the Candidate Kitaev Spin Liquid -RuCl

Tessa Cookmeyer, Joel E. Moore

Proposed effective Hamiltonians from the literature for the material -RuCl are used to compute the magnon thermal Hall conductivity, , using linear spin wave theor…

Applying Parabolic Peterson: Affine Algebras and the Quantum Cohomology of the Grassmannian

Tessa Cookmeyer, Elizabeth Milićević

The Peterson isomorphism relates the homology of the affine Grassmannian to the quantum cohomology of any flag variety. In the case of a partial flag, Peterson's map is only a surj…

Higher Rank ABJM Wilson Loops from Matrix Models

Tessa Cookmeyer, James T. Liu, Leopoldo A. Pando Zayas

We compute the vacuum expectation values of supersymmetric Wilson loops in higher dimensional representations of the gauge group in ABJM theory. We present results for the $m…

Comparative study of gyrokinetic, hybrid-kinetic and fully kinetic wave physics for space plasmas

Daniel Told, Tessa Cookmeyer, Florian Muller +2

A set of numerical solvers for the linear dispersion relations of the gyrokinetic, the hybrid-kinetic, and the fully kinetic model is employed to study the physics of the kinetic A…

A linear dispersion relation for the hybrid kinetic-ion/fluid-electron model of plasma physics

Daniel Told, Tessa Cookmeyer, Patrick Astfalk +1

A dispersion relation for a commonly used hybrid model of plasma physics is developed, which combines fully kinetic ions and a massless-electron fluid description. Although this mo…
